P 0700 - It simply means that the engine computer has noticed that the
transmission computer has a dtc in it. This causes the Pcm (engine computer) to
turn the check engine light on. You will need to have the TCM (trans computer)
checked for codes to know what to diagnose.

Is the car shutting off while driving?
Check the connections between the
PCM and TCM. PCM is behind right
wheel well and TCM is under left
side of steering wheel. If the wiring
is good and not corroded then the
TCM is bad and you need a new
one.
